The Extensible Hypertext Markup Language, or XHTML, is a markup language that has the same expressive possibilities as HTML, but a stricter syntax. Whereas HTML is an application of SGML, a very flexible markup language, XHTML is an application of XML, a more restrictive subset of SGML. Because they need to be well-formed (syntactically correct), XHTML documents allow for automated processing to be performed using a standard XML library — unlike HTML, which requires a relatively complex, lenient, and generally custom parser (though an SGML parser library could possibly be used).
XHTML can be thought of as the intersection of HTML and XML in many respects, since it is a reformulation of HTML in XML.
